ASP.Net Core + SendGrid Email not receiving

[farrukhtrs]

Hello,

I have been trying to perform a sign up email and while I am getting a success, I am not getting the email. Here is my source code:

            var response =  await _emailService.To(user.UserName)
                    .Subject("Confirm your email address")
                    .Body("Hello<br>Welcome. Please verify your email by clicking on this URL: " + confirmationUrl + "<br>Best Regards,<br>Farrukh Javeid<br>CEO", true)
                    .SendAsync();

            return response;

When I check the response, it says: Error Message: Count 0 Message Id: null Successful: true

I have checked SendGrid as well and I cannot see it's request as well. Can you please help me out with this issue?
